Methodology description
Criteria Feedback
- The research question is framed within a specific biological and real-world context, linking Vigna radiata, discrete wavelength ranges and shoot length.
- Key variables are clearly identified and control measures (light intensity, temperature, water volume, species choice) are outlined.
- Numerical justification for chosen wavelength bands and quantitative control parameters (lux or μmol m⁻² s⁻¹ measurements, lamp distance) are omitted, limiting methodological rigor.
- There is no rationale or calculation supporting sample‐size sufficiency for statistical validity.

Data processing quality
Criteria Feedback
- Data tables and graphs are clearly labelled; units and significant figures are precise throughout.
- Data processing (means, standard deviations, one-way ANOVA) is correctly carried out and reported, matching raw data.
- Consideration of measurement and biological uncertainties is minimal—no instrument error margins or propagation in statistical tests.
- Statistical reporting is incomplete (empty SUMMARY table, inconsistent wavelength category definitions), reducing analytical completeness.

Scientific context comparison
Criteria Feedback
- The conclusion is relevant to the research question, logically consistent with the ANOVA results and justified by the analysis.
- There is a connection to the accepted scientific context (action spectra, literature on light effects).
- Comparison to scientific context is superficial—no quantitative literature values are contrasted.
- Repetition of background details in the conclusion reduces focus and conciseness.

Methodological weaknesses

Improvements
Criteria Feedback
- Specific methodological weaknesses (cellophane spectral purity, lamp heating, short duration) are identified and their impacts are clearly explained.
- Improvements proposed (switch to LEDs, extend duration) are realistic, relevant and explained in terms of how they address the limitations.
- The evaluation omits discussion of sample-size limitations and uncertainty measurement improvements.
- Some improvement explanations lack detail on how extended duration would affect variance or long-term developmental observations.
